LOOM-SHUTTLE.

SPECIFICATION forming` part of Letters Patent No. 659,435, dated October 9, 1900.

Y Application led November 17, 1899 Serial. No. '73 7,268. (No model.)

T a/Z whom, it 10Q/wy concern,.-

Be it known that I, LEON W. CAMPBELL, of Woonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements'in Loom-Shuttles, of which the following is a speciicatiou.

This invention has relation to loom-shuttles, its object being to provide certain improvements therein for threading the filling 1o through the eye.

I-Ieretofore it has been the common practice for a weaver in threading the eyeto place the thread in proximity to the inner end of the eye and by placing his lips at the eye and violently inspirating to draw thethread through it. As there is constantly more or less lint and dust in the shuttle and in the eye, such foreign matter is sucked into the' throat and lungs, with the result of impairing the health, if not finally causing the loss of life of the weaver. Attempts have been made to remedy this evil by carrying the eye or aperture entirely through the shuttle, so that the Weaver may blow from the opposite side of the shuttle, and thus prevent the lint from being drawn into the lungs. This attempt has been generally unsuccessful, owing to the awkward position in which the weaver had to hold the shuttle, in addition to the time required to reverse the shuttle to bring the aperture to the lips. According to my invention, however, I provide for the weaver drawing the thread through the eye by inducing a current of air therethrough, this current of air being caused by blowing through an aperture leading from the side of the shuttle in which the eye is placed and commu nicatin g with the eye-aperture,as shall now be explained in detail.

Referring to the drawings forming .a part of this specification, Figure 1 represents in perspective View a shuttle equipped with my invention. Fig. 2 represents in plan view the eye end of the shuttle. Fig. 3 represents a horizontal section of the same. Fig. 4represents a section on the line '4 4 of Eig. 3.

The shuttle can be made after any suitable pattern, its shape or style being immaterial. As shown, it carries the spindle l for the cap 2 and is formed on its front slide with the usual groove 3 to prevent the thread from being severed as the shuttle is driven through the shed. At the end of the shuttle are bored two holes, apertures, or ducts 4 5, which coincide at their inner ends, forming the two sides of a triangle. The hole 4 is carried through the usual chamber 6, which is formed in the shuttle to receive the linger of the weaver as he places the loose end of the filling at the end of the eye-aperture, said chamber 6o communicating with the interior of the shuttle by a duct 7. In the outer end of the aperture 4 is placed a shell or bushing 8,' which extends part way into the chamber 7, and in the inner end of said aperture is fitted an 65 ejector-nozzle 9, having a contracted outlet. The hole 4, with the bushing 8, constitutes the eye for thelling,which will be drawn through it when a blast of air is blown into the aperture 5. The air passes from the last-men- 7o tioned aperture through the ejector 9 and induces such a current of air from the chamber 6 through the eye that when the thread is placed Yin said 'chamber it will be carried through the eye instantly, even though it is some little distance from the inner entrance to the bushing. By boring the aperture from the side of the shuttle in which the eye is located the weaver is not compelled to reverse the shuttle, and the operation of threading 8o the eye is performed without loss of time and with little or no exertion.

By exhaling' the breath in drawing the thread through the eye instead of inhaling it the weaver does not breathe into his lungs and bronchial tubes lint, dust, or other foreign material to the detriment of his health.

Having thus explained the nature of my invention and described a way of constructing and using the same, though without attempt- 9o ing to set forth all of the forms in which it may be made or all of the modes of its use, what I claim, and desire to secure by Letters Patent, is-

1. A shuttle havingathread-eyeon the side thereof, and a supplemental passage leading from the side mentioned for permitting the. induction of acurent of air through saideye.

2. A shuttle having two converging apertures Vcommunicating with each other and ioo opening on the same side, one forming a thread-eye and the other serving for the inmunicating with one of said duels, andan ejector located at the inner end of the lastmentioned duct.

In testimony whereof I have atxed my signature in presence of two witnesses.

LEON W. CAMPBELL.
